Description

Combined desk type energy-saving curve saw

Technical field

The present invention relates to a kind of electric tool, specifically a kind of energy-conservation combined desk type energy-saving curve saw.

Background technology

The sweep-saw of prior art mainly divides hand-held and desk-top two kinds, known desk-top sweep-saw in actual production and the deficiency that exists in using be that volume is big, complex structure, machined piece are many, the processing cost height, the big power consumption of power of motor is high, is difficult for storage and transportation etc.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, be easy to processing, do not have machined piece substantially, the combined desk type energy-saving curve saw that processing cost is low.

Energy-saving curve saw of the present invention, its structure is made up of base and saw bow, be provided with the miniature high-speed motor in the base, big belt pulley and eccentric wheel, eccentric wheel and big belt pulley are arranged on the two ends of Pulley shaft, Pulley shaft is fixed among the base by bearing block, belt pulley is connected with the small belt pulley of miniature high-speed motor shaft end in being arranged on base by belt, be provided with a groove at the middle part of base, the right side of groove has a groove through hole and communicates with base inside, the right-hand member of saw bow bottom puts in base inside from the groove through hole on groove right side, the right-hand member of saw bow bottom is provided with capacity eccentric bearing chute and following saw blade clamper, capacity eccentric bearing on capacity eccentric bearing chute and the eccentric wheel joins, the saw bow upper right end is provided with the saw blade clamper and is connected with the upper end of saw blade, the middle part of saw blade is through among the saw blade through hole in the middle of the workbench of base upper surface, the left end of saw bow bottom is provided with hinge axis, and hinge axis is fixed on the saw bow pillow block of base 1 left end by the hinge axis gland.

Excellent effect of the present invention is, because the motor of sweep-saw just drives saw blade and up and down reciprocatingly works, so adopt the miniature high-speed motor to replace the high-power low-speed motor of prior art by big small belt pulley speed change, because the little power consumption of miniature high-speed motor, volume is little, so can reduce the volume of fuselage after improving greatly, and can be directly motor be installed among the base, make complete machine compact more attractive in appearance, main is to greatly reduce manufacturing cost, in addition, because saw bow can conveniently be pulled down, so volume is little, packaged convenience, do not take up space, can effectively reduce freight and memory space, thereby, make this sweep-saw more competitive on market.
